User reviews

Excellent App

I have found SubStreamer to be the app with the best combination of features, usability, and stability. I tried a lot of apps, including some that are still being developed, but this one was the only one that wor my rd consistently and could donate all the things. I wanted. Good wotk!

Nect button not working

Hi! I found a bug in the app. When I play music from the Songs tab, the Next button doesn’t work. It won’t skip to the next track, even though the song is playing normally. Could you please look into this issue? Thanks for all your hard work on the app.

Falta PT-Br

O app parece bom, mas falta suporte ao idioma PT-BR e também suporte a lyrics, pra acompanhar a letra da música, pra ele ficar 100%

Great experience!

I just recently got into self-hosting my collection and I needed an app to replace the other streaming apps I was paying way too much for. The interface is intuitive. The only feature I wish it had was a way to automatically download favorite songs or just make a playlist since you can download playlists. Maybe that would be harder since playlists are created and saved on the server-side? Still, this app was the first one I tried and I have been loving it!
